Error: "The following classes could not be found: - android.support.v7.widget.GridLayout" after upgrading Android SDK Tools

An app has been using android.support.v7.widget.GridLayout for a while without any problem. I upgraded Android SDK Tools to 22.0.1 this morning. Now, it seems that the app cannot see the library anymore. The Java code has the following error:

The import android.support.v7.widget cannot be resolved

I tried to add a GridLayout to a dummy layout file by dropping GridLayou to it thinking this would help configure the project properly for using GridLayout. However, this generates the following error:

The following classes could not be found:
- android.support.v7.widget.GridLayout

I have restarted Eclipse multiple times and cleaned all projects. Gridlayout_v7.jar is under Android Dependencies and the path is correct.

What should I do to repair the configuration of the project so that android.support.v7.widget.GridLayout can be used?

Computer OS: Windows 8 Pro

CPU: Intel i5

Important Change

It has been removed as of API 25.0.0:

You should replace android.support.v7.widget.Space with android.support.v4.widget.Space

See here

android.support.v7.widget.Space has been removed. Usages should be replaced with android.support.v4.widget.Space.

It probably updated your default support v4 lib and now the on in your projetc/lib folder is probably a different version from the one inside v7.

Delete the support v4 jar file in your project/lib folder.

You can have it there and work with the support v7 lib, but v7 already has a v4 lib and they must have the same version to work.

Remove the v4 jar file in your lib folder, then add the v7.

Edit you project's (and library project's too) .classpath file like this:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
    <classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK"/>
    <classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.DEPENDENCIES"/>
    <classpathentry exported="true" kind="con" path="com.android.ide.eclipse.adt.LIBRARIES"/>
    <classpathentry kind="src" path="src"/>
    <classpathentry kind="src" path="gen"/>
    <classpathentry kind="output" path="bin/classes"/>
</classpath>

Apparently, you do not have the Android library project containing GridLayout referenced from your project, perhaps because the old reference is now broken.
